In some instances, it is desirable to construct one of the sections 32 and 33 of greater depth than the other in order to provide room for an aperture 44 disposed more centrally than as shown in Fig. 6. The resultant shifting of the yoke section 34 one way or the other and the consequent shifting of the aperture 26 is, of course, a matter of mechanical detail.

The installation of the cap assemblage is as follows:

'I'he yoke member 30 is disposed Within the cap 2| in a position so that the projections 31 and 38 are opposite the slots 25. The Wedge 3l is inserted through the aperture 26 and is moved inwardly until the Wedging portion engages and spreads the strips 35 and 36 suihciently to move the projections 31 and 38 into the slots 25 to positions flush with the exterior of the skirt 23 (Fig. '7.) The cap assemblage 2U is then disposed in' the end of the case i3 with the shoulder 24 -engaging the end thereof. The Wedge 3| is driven downwardly until it assumes the position shown in Fig. 4 which further spreads the strips 35 and 36, thereby moving the projections 31 and 38 into the slots fil and into iiush relation with the exterior of the case i3. It is, therefore, evident that the casing i3 is closed in a positive manner so that the cap assemblage cannot be accidentally displaced and lost. Further, the cap assemblage 20 merges smoothly with the case I3 presenting no sharp corners and no obstructions.

A cap assemblage has been provided which fuliills all of the objects and advantages sought therefor. It to be understood, of course, that the several elements of the cap assemblage are constructed o1 material suitable for such elements, the yoke section ill of he yoke member 38 being of a resi. ent material in order to expedite dismantling of the cap assemblage 23.

It is to be understood that the foregoing description and accompanying drawing have been given by way of illustration and example and not i or purposes of limitation, the invention being limited only by the claims which follow.

What is claimed is:

l. In a device of the kind described, a cap, and means for maintaining said cap in operative disposition relative to a bookbinder case inciuding a yoke member positively engaging the cap and the case.

2. In a device of the kind described, a cap, and means for maintaining said cap in operative disposition relative to a bookhinder case including a yoke member having opposed projections, and a wedge maintaining said opposed projections in engaging relation with the cap and the case.

3. A cap assemblage for closing an end of a case of a bookbinder comprising a cap having aligned slots in opposed sides, a yoke member having movable oppositely disposed projections, and a Wedge, said Wedge being adapted to move said projections into said aligned slots.

1i. In a device of the kind described, a case having aligned slots in opposed sides forming a. part of a bookbinder, and a cap assemblage disposed in closing relation in an end of the case, said cap assemblage comprising a cap having aligned slots in opposed'sides, a yoke member having oppositely disposed projections, and a Wedge, said projections being disposed in said slots of said cap and said case and being maintained therein by said Wedge, thereby positively locking said cap assemblage in closing relation with said case. v

5. A cap assemblage for closing an end of a case of a bookbinder comprising a cap, a member` disposed within said cap, and means for moving said member into securing engagement with a case end to hold said assemblage in operative disposition relative to such case.

6. In a device of the kind described, a case forming a part of a bookbinder, a cap assemblage disposed in closing relation in an end of the case comprising a cap, a member disposed within said cap in securing engagement with said cap and said case, and a second member engaging said member and maintaining it in securing engagement.

7. A cap assemblage for closing an end of a case of a bookbinder comprising a cap, a iirst member within the cap including spaced portions. and a second member Within the cap in engagement with the spaced portions maintaining said first member in a position locking the cap to the end of the case of a bookbinder.
